I just cleaned my asv, egr valve, and I wanted to reduce the amount of oil into the intake to help keep it clean. It did have a minimum oil sludge (1/8" ) at opening of the intake. Parts needed: Ebay- aluminum oil catch can 0.5L 19mm / 3/4 barbs in and out, drain on bottom. On sale $18.95 shipped Lowes- 1" brass pex elbow- tight fit on 3/4 hose - $3 Lowes- 3" u bolt - $3 Autozone- 4' 3/4 heater hose - $6 - this will be upgraded to black braided hose. Laying around - hose clamps, 1" x 28" aluminum angle, bolts, nuts, washers, extra BRM valve cover to air cleaner tube and air cleaner drain tube. I am going to document this in multiple posts, so be patient!
